These animations show NASA's Voyager spacecraft encountering Jupiter, Saturn, Uranus and Neptune on their grand tour through the solar system. The artist's renderings were made based on navigational data from Voyager 1's visit to Jupiter and Voyager 2's visits to Saturn, Uranus and Neptune. The shot of Voyager leaving the solar system is based on Voyager 1's trajectory.

Both Voyager spacecraft were launched in 1977 and are on their way out of the solar system.

The Voyagers were built by NASA's Jet Propulsion Laboratory in Pasadena, Calif., which continues to operate both spacecraft. JPL is a division of the California Institute of Technology in Pasadena. The Voyager missions are a part of the NASA Heliophysics System Observatory, sponsored by the Heliophysics Division of the Science Mission Directorate.
